1 Introduction
HeiTel CamLine
Video Transmission
Thank you for selecting HeiTel for this high-quality security product. CamLine
was specially developed for CCTV security applications.
Only high-quality components were used in CamLine which satisfy the strict-
est security requirements and guarantee years of problem-free operation. The
device is housed in a robust steel housing which can be free standing or wall
mounted.
HeiTel's years of experience as a pioneer in the field of digital video has en-
abled the development of a carefully designed, reliable product with a high
quality to cost ratio for a wide range of applications.
What is CamLine? CamLine is a digital video transmitter which can transmit up to two camera
signals in compressed form over the public telephone (or computer) network.
CamLine is used for the connection of external transmission devices such as
modems, customer supplied TA´s, TCP/IP Alarm Adapters, etc.
Function Up to two colour or mono cameras can be attached to each CamLine device.
The two “camera alarm” inputs are assigned to the two video inputs and
serve to create dial up scenarios when triggered. In the event of an alarm ac-
tivation CamLine transmits the “alarm image” (the image from the moment
in time that the alarm took place) from the relevant camera back to the re-
ceiving PC, and then proceeds to transmit live images from that camera, or
as requested by the user/software configuration.
A relay output is available for the remote control of external equipment,
doors lights barriers etc.

Direct connection between CamLine and a PC
Null Modem cable The CamTel®Windows Software and CamLine automatically recognise if a
null modem connection is being attempted. This is recognised on the basis of
a special code in the cable plug (pin assignment see below) which is read and
evaluated at the COM port when the device is switched on or when the Cam-
Tel®Windows Software is started. Please be certain only to use the original
null modem cable from HeiTel or an appropriately modified cable. No direct
connection is possible with standard commercial null modem cables.
Auto-baud recognition allows a connection at 115200 Baud, even when
CamLine is set to 230400 baud.
Pin Assignment of the HeiTel Null Modem Cable
Status information for CamLine
Display The green LED indicates that the transmitter is switched on.
The yellow LED can signalize various conditions/errors by means of a se-
quence of flashes.
Conditions and
Errors
Off but flashes on for a short period = Offline
On but flashes off for a short period = Online
1 x flash everything is OK, transmitter is operational
2 x flash internal hardware fault
3 x flash same as 2x flash
4 x flash same as 2x flash
5 x flash connected modem / ISDN terminal adapter could not be addressed.
Check the connections and, when necessary, the dial prefix set in the trans-
mitter settings. You will also receive these errors when the transmitter is
switched on without a modem / ISDN terminal adapter or zero-modem cable
being connected. Normally, you should connect the modem / zero-modem
cable before switching on the device.
6x flash the receiver could not be reached by an alarm call. The reason for
this could be that the receiver program is not running or that the line is busy.
Ensure the null mode cable is connected to both PC and CamLine before ap-
plying power to the CamLine or starting the CamTel®Windowssoftware.

Control Interface
All control inputs and outputs on the CamLine devices are realised in the form
of easily accessible screw/clamp connections.
The inputs are decoupled by means of capacitors to protect against faults and
are connected to ground (pin 3).
The settings menu is used to configure all inputs to the type of signal contacts
used. The device is compatible with signal contacts which have normaly open
or normaly closed contacts. The two camera signals allow CamLine to react
to signaling events triggered by external devices (such as door contacts, mo-
tion detectors, alarm system). When set, the transmitter box establishes a
connection with a CamLine receiver and transmits images from the respective
location.
Camera Signal
Save alarm image If a camera alarm is activated, an image from the respective video input will
be saved. This is available as an alarm image in the event that a connection is
established and is transmitted as the first image.
Establishing a
connection
Each camera alarm can be set individually to establish a connection with the
receiver or not when it is activated.

3 System Description
CamLine 15
Display status When online, the statuses of the camera alarm inputs are indicated by red
text in the camera buttons in the receiver software. This allows the user to
easily identify which cameras are sending signals at any given time.
Output (relay)
The transmitter box is equipped with a relay output for general switching pur-
poses. The relay can be configured in the software setup screen to be latching
or non latching switches.
When set as a latching switch, the relay state changes with each click on the
button (e.g. lighting on/off). When the relay is set as a non-latching switch,
the current relay status changes for the duration indicated in "Closed/s" (e.g.
for electro-magnetic door openers) each time the button is clicked.
There are two additional operating modes for the relay:
Switch on fault A relay can be set as a fault relay to signal faults, such as failed connection
attempt. The relay is always active in release state when set as a fault relay,
so that power failures are also signalled (the relay breaks in the event of a
power failure).
Switch on
connection
In order to signal that CamLine is currently online, the relay switches on for
the duration of the connection and switches off at the end of the connection.
For example this function allows lights to be activated automatically in the ar-
ea being monitored. When set to "Switch on connection" the relay button
is deactivated on the CamLine receiver screen.
Loading the Factory
Settings
To load the factory settings, CamLine must first be connected to its own PC
using the nullmodem cable.
Then start the terminal software or Hyper Terminal from Microsoft. The ter-
minal program must be set to 115200 baud.
Now switch CamLine on. A "*" appears on the terminal screen. Enter
"cl-init"within 5 seconds. Shortly thereafter, "INIT OK" appears onthe
screen and the green LED goes off.
As soon as the green LED once more lights up, the factory settings are loaded.
Activations at the camera alarm must be for at least 1 second in order for
CamLine to recognise them properly.
Some relay settings do not take effect immediately, rather after the connec-
tion is terminated (e.g. deactivation of function Reset Offline).

3 System Description
16 CamLine
Pin assignment of the control interface
Inputs must be connected to ground (pin 3) by means of potential-free con-
tacts. The minimum contact time is 1 sec in order to ensure that switch con-
ditions are properly recognised.
Video Inputs
The two video inputs are BNC connections. A colour or monochrome signal
can be connected here. Almost all standard, commercially-available cameras
can be used, providing they correspond to the CCIR standard (PAL or NTSC).
75 Ohm The impedance of the video input is set 75 Ohm (on).
Adjusting the video
signal
The picture quality should be checked at the receiver. The settings for bright-
ness and contrast can be adjusted at the receiver for each camera.

4 Connection of External Devices and
Components
This chapter contains information on the use of external equipment with
CamLine. The use in transmission networks and the preparation of modems/
TAs is covered here.
4.1 Data transmission equipment
Suitable Transmission Networks
Image transmission with CamLine can be achieved via a number of transmis-
sion methods. The "modem" port serial interface available for connection to
transmission devices for ISDN, PSTN and GSM networks. Transmission over
Ethernet computer networks can easily be achieved by using the TCP/IP Alarm
Adapter, which acts as a transmission unit for Ethernet networks. Dedicated
connections can be established with dedicated line modems over simple two-
wire twisted pair copper lines, independent of public phone networks.
Interface Settings
Local Baud Rates The local baud rate refers to the interface speeds of the serial interface be-
tween the modem/TA and CamLine (not to the transmission rate on the trans-
mission medium).
In most cases, e.g. for the transmission over ISDN lines or for null modem con-
nections directly to the PC, the setting 115200 baud is correct.
Exceptions must be made for:
■GSM transmissions with the Siemens Module M20 (19200 baud).
■Null modem connections to PC systems with COM ports that only support
57600 baud.
■Analogue connections with specific modems which must operate at 57600
baud.
Modem Settings
The highest degree of transmission security is achieved when the connected
transmission device (modem/TA, ...) is pre-configured on the PC. The device
can be pre-configured by means of a terminal program such as Hypertermi-
nal, which is included with the Win 95/98 operating systems. The required AT
command set is partially modem-specific and is described in any modem
manual. The following information applies to general modem configuration
for operation with CamLine. As supplementary information, the initialisation
strings are included for all devices which have been factory tested and are rec-
ommended. The list of usable devices is constantly updated and expanded.
Up-to-date overviews can be acquired from your specialised dealer.
